中文摘要：储量丰富的生物质作为一种可再生的有机资源,可通过化学反应转化为高附加值的化学品或燃料,有助于降低对化石能源的依赖.5-羟甲基糠醛(5-hydroxymethylfurfural,HMF)是一种关键的生物质平台分子,其含有醛基、羟甲基和呋喃环,具有优越的化学性能,可通过氧化、加氢、开环水解、醚化和聚合等化学反应转化为一系列高价值的衍生物,可应用于医药、材料、化工、生物燃料等领域.近年来,光催化作为一种经济有效的绿色化学方法不仅克服了传统热催化的缺点,还应用于生物质转化.本文系统地综述了近年来光催化/光电催化HMF的研究进展.同时,本文重点关注了光催化氧化过程中活性物种对HMF选择性的影响和用HMF氧化取代动力学迟缓的水氧化以促进光解水产氢.最后,还对未来的研究方向进行了展望,包括探索多步骤反应策略以提高2,5-呋喃二羧酸(FDCA)的产率,深入研究光催化HMF氧化反应动力学和催化活性位点以全面理解HMF的光催化氧化机制,以及优化光催化剂实现高效选择性的HMF转化,为可持续能源、生物质转化和液体生物燃料领域提供新的创新解决方案.

外文标题：Research progress in photocatalytic/photoelectrocatalytic conversion of 5-hydroxymethylfurfural

外文摘要：Abundant biomass,as a renewable organic resource,can be transformed into high-value chemicals or fuels via chemical reactions,which contributes to a reduction in dependence on fossil energy.5-Hydroxymethylfurfural(HMF)is a significant biomass platform molecule composed of an aldehyde group,a hydroxymethyl group,and a furan ring.It exhibits outstanding chemical properties and can be converted into a range of high-value derivatives using oxidation,hydrogenation,ring-opening hydrolysis,etherification,and polymerization reactions.These derivatives have applications in medicine,materials,chemicals and biofuels.Photocatalysis,which is gradually utilized in biomass conversion and surpasses the limitations of traditional thermal catalysis,has emerged as a cost-effective and environmentally friendly method in recent years.This review provides a systematic summary of the recent research progress on photocatalytic/photoelectrocatalytic conversion of HMF,and concerns the way that reactive radicals affect the selectivity of HMF during photocatalytic oxidation and how HMF oxidation promotes photocatalytic water splitting to improve the slow kinetics of water oxidation.Finally,this review highlights future forthcoming research objectives,such as exploring multi-step reaction strategies to increase the yield of FDCA,in-depth investigation of the kinetics and catalytic active sites in the photocatalytic HMF oxidation process to understand the mechanism of photocatalytic oxidation comprehensively,and optimization of photocatalysts to achieve efficient and selective HMF conversion.All of the above show the potential to provide innovative solutions in the fields of sustainable energy,biomass conversion,and liquid biofuels.
